Quick answer: The official MemoFix checkout names five ingredients: branched-chain amino acids (2:1:1), Bacopa monnieri, Rhodiola rosea standardized to 3% salidroside, L-theanine and Panax ginseng. Doses are shown only in a label image, so check your bottle.
What we know

An honesty note first
Honesty note: the official checkout names five ingredients but shows the Supplement Facts only as an image we could not read, so doses are not confirmed here. Other websites list a different formula (with Lion's Mane, ginkgo and huperzine A); we go by the checkout. Always check the label on your bottle.
For comparison, research doses are about 300 mg a day for Bacopa extract, 200 to 600 mg for Rhodiola, 100 to 200 mg for L-theanine and 200 to 400 mg for ginseng extract. If your label shows similar amounts, the formula is in a research-informed range.
The five named ingredients
Bacopa monnieri extract
An Ayurvedic herb with the best memory evidence on this list. Reviews of trials using about 300 mg a day of standardized extract for 8 to 12 weeks found modest improvements in recall and attention. It can cause stomach upset.
Bacopa research on PubMedRhodiola rosea (3% salidroside)
An adaptogen studied for mental fatigue and stress, usually at 200 to 600 mg a day. Results are mixed but some trials show less fatigue under stress.
Rhodiola research on PubMedL-theanine
An amino acid from tea linked to calm focus. Studies typically use 100 to 200 mg, often paired with caffeine.
L-theanine research on PubMedPanax ginseng extract
Reviews find small, inconsistent effects on memory and mental fatigue, usually at 200 to 400 mg of extract. It can affect blood sugar and interact with blood thinners.
NCCIH on Asian ginsengBranched-chain amino acids (2:1:1)
Leucine, isoleucine and valine. Mainly studied for muscles; a few studies look at mental fatigue during exercise, with limited results.
BCAA research on PubMedHow strong is the evidence?
| Ingredient | Main idea | Evidence for memory or focus |
|---|---|---|
| Bacopa monnieri | Memory recall | Moderate, after 8 to 12 weeks |
| L-theanine | Calm attention | Limited, stronger with caffeine |
| Rhodiola rosea | Mental fatigue | Mixed |
| Panax ginseng | Fatigue, memory | Mixed, small effects |
| BCAAs | Exercise fatigue | Weak for cognition |
